From 748c434bfa956e3ac64793d14d3bdbe7befcb901 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Thu, 29 Jan 2015 07:17:18 +0000 Subject: [PATCH] i40evf: disable NAPI polling sooner When closing the interface, disable NAPI polling before any other activities. This fixes an occasional panic during close caused by the driver trying to delete and clean rings at the same time.
